1.Hyper Estraier是一个用C语言开发的全文检索引擎,他是由一位日本人开发的.工程注册在sourceforge.net(http://hyperestraier.sourceforge.net).
2.Hyper的特性:
高速度,高稳定性,高可扩展性…(这可都是有原因的,不是瞎吹)
P2P架构(可译为端到端的,不是咱们下大片用的p2p)
自带Web Crawler
文档权重排序
良好的多字节支持(想一想，它是由日本人开发的….)
简单实用的API(我看了一遍，真是个个都实用,我能看懂的，也就算简单了)
短语,正则表达式搜索(这个有点过了,不带这个,不是好的Full text Search Engine?)
结构化文档搜索能力(大概就是指可以自行给文档加上一堆属性并搜索这些属性吧?这个我没有实验)
